"""
Schemathesis contract tests.
Generates requests from the OpenAPI spec and verifies that no input causes a 5xx.
Currently scoped to `not_a_server_error` only — full response-schema conformance
(including undocumented 401 responses) is blocked by DEBT-020 (missing error
response declarations across all protected endpoints). Once DEBT-020 is resolved,
replace the checks list with the default (remove the argument) for full compliance.
Requires DECNET_DEVELOPER=true (set in tests/conftest.py) to expose /openapi.json.
